I am using my new AC200Max and so far so good. How long can the inverter handle >900 W on the one PV port, using a pair of rigid bifacial 440W-460W connected in series?
@bluetti_res408cagmailcom Our machine has overvoltage and overcurrent protection. The processing time for overvoltage protection is 200ms. Power through the machine will not be greater than 900w, do not worry.
As long as you do not exceed the max voltage of MPPT input of 150V (Voc) you can load as many solar panels as you wish. There are folks who over panel and load up to 2000w of panels across the inputs and it is OK for days on end.
If you exceed Voc of 150v, damage can occur. Do not do that.
